Many pieces of Watt Pottery were produced with lids. Over the years many of these lids were broken or damaged. Some lids have become quite valuable simply because so many were destroyed over the years. Many Watt Pottery Lids are at times mismatched with the wrong pieces so you have to pay attention and know the molds to catch this at times. Some Watt Pottery Lids in Mint Condition bring a very nice premium in todays market.
